经过磨损的不等距螺旋输送辊的螺纹是一条“等变距螺旋线”。
The thread of abraded unequal spiral shifting roller is actually a "uniform increasingly dispersing-ratio spire".
用测量数据求出了一条符合要求的不等距螺旋线方程，并给出其BASIC程序。采用划线、手动看线走刀配合机床进给的铣削加工工艺方法加工不等距螺旋输送辊。
In this paper, according to the data of measurement, a new equation of helixices and the BASIC program is proposed, and a manufacture method is discussed.
